Stig-Ake Jonsson/AFP/Getty ImagesIsrael's Harel Levy finds it a lonely scene as only 300 'special guests' were allowed to attend the Davis Cup matches in Malmo, Sweden, because of security issues.

Only 300 special guests were allowed inside the hall to watch Ram and Hadad save two match points before Lindstedt's drop shot winner clinched the match. Malmo officials had closed the venue to the public, citing security risks and protests against Israel because of the recent offensive in the Gaza Strip.

Earlier in the week, Ram said it was a "stupid decision" to play the match behind closed doors.

The clashes erupted after about 7,000 people gathered at a downtown square to hear speeches condemning Israel's offensive in Gaza and urging support for Palestinians.

Organizers of the "stop the match" protest had said the demonstration would be peaceful, but extreme-left activists had vowed to disrupt the match.

About 100 people were apprehended and at least six were formally arrested for rioting, Malmo police spokeswoman Ewa Westford said. There were no reports of injuries.

About 1,000 police from southern Sweden were deployed in Malmo, Sweden's third-largest city, to keep the protesters from entering the arena.

The Israelis rallied after dropping the first set but Aspelin and Lindstedt raised their game in the third.

"They played a good tiebreak to win the third set," Ram said. "And they didn't give us any chances in the fourth."

The Swedes, who were favored to win the doubles, were relieved to head into the reverse singles on Sunday with a one-point advantage.

"If we hadn't won this match, things would have looked more difficult on Sunday," Lindstedt said.

Hadad, ranked 980th in singles and 347th in doubles, was called up to play for Israel.

"We have two injured players, and I was next," Hadad said.

On Friday, Johansson put Sweden ahead with a five-set win over Levy before Sela evened the series with a five-set victory against Vinciguerra.

It marks the second time a Davis Cup series was played without fans in Sweden. In 1975, two years after a military coup in Chile led by Augusto Pinochet, Sweden played Chile in an empty stadium in Bastad.
